Break away valves

Break away valves


The break away valve is a safety accessory used on both gas phase and liquid phase lines which, in case of unexpected departure of a truck with hose or loading arm connected, automatically determines the breakage of the body in a specific weakened point. Once broken the main body, two shutters moved by springs determine the interruption of the flow on both sides..
The adoption of this solution prevents major damages to mechanical pipelines and equipment and reduces to a minimum quantity the leak of gas in the environment.
